Video content viewing apparatusVideo content viewing apparatus description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20090112933, Video content viewing apparatus. Brief Patent Description - Full Patent Description - Patent Application Claims
The present application claims priority from Japanese patent application JP2007-276346 filed on Oct. 24, 2007, the content of which is hereby incorporated by reference into this application. (1) Field of the Invention The present invention relates to a video content viewing apparatus using metadata to achieve all kinds of functions for users to watch video contents. (2) Description of the Related Art Most TV sets nowadays not only allow viewers to watch broadcast programs, but also enable the viewers to extract (or search) important scenes from a program or to search for a wanted program according to a keyword they inputted. There have been the following suggestions regarding the technique. Japanese Patent Application Publication No. 2006-165650 relates to the management of collateral information (metadata), which is achieved by adding an item that shows whether each item in the metadata of each content is corrected, so as to indicate a contrivance for decision of correction propriety of metadata of contents and to manage each of various items in the metadata of the contents on the item-to-item basis. Japanese Patent Application Publication No. 2002-152692 relates to a technique for obtaining information on a product associated with a broadcast program. According to the disclosed technique, a website address on the Internet of an advertiser who supplies product(s) or service(s) that viewers might be interested in when watching a broadcast program is transmitted as associated information simultaneously with a broadcast, so the viewers can easily obtain information associated with any subject in which they are interested in. Japanese Patent Application Publication No. 2003-158726 relates to a technique for providing information associated with a broadcast program using the Internet. According to the disclosed technique, viewers receive information for specifying a service area along with the channel number and the date of broadcast, so they can easily acquire the information relevant to a broadcast program independent of the service area. TV sets today are required to be able to provide video contents that include broadcast programs and relevant information to a viewer in one of various forms selected according to the view preferences. Hereinafter, this function will be referred to as a “video navigation function”. Both regular and special functions have been suggested for the video navigation function, which include regular forms like “Watch an On-air program” or “Watch a recorded program”, and special forms like “Play back highlight in a video content”, “Search a scene in a video content”, “Search for information relevant to video content”, etc., yet new functions are expected to be added in the future. For example, if video contents can be presented by theme designated by a viewer, it would offer even more improved convenience of use. To implement the video navigation function, it is necessary to set descriptions of conditions for executing different functions for each video content as a target (the description is called “metadata”). For instance, metadata for the highlight playback function requires location (time information) of a highlight scene of interest in each program. Preferably, metadata on a target content is kept in a TV set that has the video navigation function or in a recording device that records video contents. However, with a multifunction trend in the video navigation function and an increasing demand for target contents, a huge amount of metadata is also required. In that case, making and retaining such a huge amount of data only on the side of a viewing apparatus (TV set) could be a heavy load on the hardware configuration of the terminal, memory capacity, and processing power of a processor for example, and this problem is led to an increase in development costs of terminal devices. Therefore, there is a need to establish a new system to efficiently achieve the video navigation function. Meanwhile, deterioration in quality is another concern that comes along with the increased amount of metadata because the video navigation function cannot be executed properly unless optimum metadata is acquired. Thus, a special function for verifying completeness of metadata and for correcting an incomplete portion is needed. None of the aforementioned patent documents considers ways to manage and operate metadata in diverse forms of a video content. It is, therefore, an object of the present invention to achieve a multifunction video navigation display without adding an extra load onto hardware or software of a viewing apparatus. In accordance with an aspect of the present invention, there is provided a video content viewing apparatus that executes all kinds of viewing functions (video navigation functions), including: a memory unit for acquiring video contents together with metadata to execute a video navigation function from an external device and storing them; a metadata analysis unit for selecting a video navigation function and for analyzing the acquired metadata; and a navigation unit for executing the selected video navigation function according to an analysis result provided from the metadata analysis unit. In an exemplary embodiment of the present invention, the metadata analysis unit includes: a video navigation function selection section which allows a user to select a video navigation function; and a metadata verification unit for verifying completeness of the metadata based on a metadata description rule and for correcting and complementing an incomplete portion of the metadata. In an exemplary embodiment of the present invention, as one of the video navigation function, the navigation unit has a function of viewing a video content relevant to a specific theme being designated, and the metadata analysis unit includes a metadata synthesis unit for collecting metadata relevant to a specific theme to synthesize new metadata associated with the theme. In accordance with the present invention, a multifunction video navigation display can be achieved without adding an extra load onto hardware or software of a viewing apparatus. At this time, even if metadata for executing the function is incomplete, it can be complemented to realize the normal video navigation function.
